ELECTRIC DEVICE FOR LIGHTING GAS.

SPECIFICATION forming part of Letters Patent No. 305,726, dated September 23, 1884.

Application filed January 17. 1884. (X model.)

To all who/1t it may concern:

Be it known that I, HoRATIo N. WiLLiAMs, of the city and county of Providence, State of Ithode Island, have invented certain new and 5 useful Improvements in Electric Lighters, of

which the following is a specification.

My invention has for its object to provide a, simple and efficient substitute for frictionmatches in lighting blow-pipes.

10 My invention consists in an electric blowa pipe lighter, constructed and arranged as hereinafter described and claimed. e In the accompanying drawings, Figure 1 is aperspective View of a jewelers work-bench with my improvements applied. Figs. 2, 3,

4i, 5, and 6 are views of certain details of construction hereinafter described.

In manufacturing establislunents, particu larly those devoted to the making of jewelry,

it is necessary to burn many blow pipe flames,-

and such lights are frequentlylighted and extinguished and relighted. Heretofore such establishments have been obliged to keep .large supplies of friction-matches constantly 2 5 on hand, and the presence of such quantities of unused matches, and the carelesshandling of the burned matches as well, have greatly increased the liabilities of fire in such establishments; hence the necessity of some superioro substitute for the matches. In the said drawings, A designates a jewelers work-bench 5 B, a gasservice pipe b, a swinging gas-bracket; b, a burner-tube; I a burner-tip, and b a key for turning the gas off and on. No novelty is claimed in these parts per .50, and they may be of any suitable or pre-- l'erred form. C designates a blow-pipe; one end of which (shown resting on the bench A) may be con- 40 nected with any suitable air-forcing apparatus; or such end may be arranged to be placed in 'the operators mouth, as preferred. The opposite end of .the'blow pipe-is provided with a metallic nozzle, 0, of any suitable or pre- 25 ferred form.

C designates a flexible gas-tube, which leads from a metallic connection, as, with the bracket 7), to a metallic connection, 0:, with the nozzle c. The connection at x is provided with a key, k,'which causes .the gas to flow either to the burner or to the blow-pipe tube, or to both.

D designates a battery of any suitable form, and d designates the helix thereof.

Z designates the groundwire, which leads from the battery D to the pipe A, whence current communication extends to earth.

E designates the conductor or lighting wire, which extends from the helix (Z upward through an aperture in the bench A. At its free end the wire E is provided with a protecting and insulating sheath, F, which is provided with a flap,f, as shown in Fig. 5.

For the purpose of increasing the degree of protection afforded to the naked end or tip 6 of the wire E by the sheath F, the latter may 6 5 be provided not only with the flap f, but also with the guardf. (See Fig. 6.)

G- designates a clip for holding the blow-pipe nozzlewlien said pipe is not in use, said clip being secured to the bracket 1) or to any other 0 convenient object. Fig. at, is a similar clip, which is designed to be secured to thebracket 'or to any other convenient object for the pur pose of holding the wire E when idle. These clips embrace their supporting obj ect,to which they, are each secured by a screw or pin, as shown. The nozzle or wire, as the case may be, is clasped between the extremities of the clip, as shown, and when the clip is secured to the bracket it forms a. part of the electrical S0 connection between the bracket and the battery through the blow-pipe.

As previously stated, the tip I)" may be of lava or other suitable material. In any event the tip may be surrounded up to the level 'of its out with a collar, h, secured to the tube 2), as indicated in Fig. 2.

' In Fig. 3 I have illustrated a longitudinal section oftheblow-pipe gas-tube C, in, order to represent the form of electrical conductor used 0 therein, the tube 0 being shown as drawn out straight for purposes of economy in space upon the sheet. c designates a piece of resilient metal coiled at its middle section and turned up at its ex- 9 5 tremities over the ends of the tube.

The purpose in coiling the piece 0 is to render it flexible, so that it shall not chafe the tube 0, and said piece is resilient, so as to support and strengthen the tube. Theends of I00 the piece 0 are bent over the ends ol'thctube, in order to effect a contact with the bracket,

and consequently an electrical communication between the ends of the piece 0 and the metallic connections .r :r. I would also state that the purpose of the shez'r-th IF isnot only to pro tect the naked end or tip 0 of the wire E, butalso to prevent any waste of the current which would result from any contact between the tip and the metal portions of the bench A.

The operation of the device is as lollows: The gas is turned on by means of the key If, and i'lows into the bracket, and thence to the bu rncr, (let us suppose.) The workman takes the wire in his hand and brings the naked tip '0 near to the upper edge 01' the collar 71, and

the spark which is emitted ignites the gas which lights the workmans bench. "\V hen the blow-pipeilaineisto be lighted,the operation is similar. The workman adjusts the key 7: so as to shut ol'tthe gas from the burner, or so as to admit the gas to both the burner and blowpipe. lzlc then presents thetip c to the end of the nozzle, and thus ignites the gas.

Haring thus described my invention, 1 clain1 .l. The combination of ablowipe, a battery with which said blow-pipe is electrically con nected, and a lighting-tip electrically connected with the battery and arranged to con1-' plete the circuit by contact with the blow-pipe, substantially as described.

2. The combination, with a gas bracket placed in electrical communication with abattery, of a blow-pipe placed in electrical com inunieation with the bracket, and a lightingtip placed in electrical communication direct l y with the battery, substantially as described.

3. The combination, with the gas-bracket placed in electrical communication with the battery, of the blow-pipe 0, having the tip 0, and the branch 0, containing the electrical conductor, and the tip 0, electrically connected directl y with. the battery, as described.

4. The combination,with the braeketcarrying the clip G, of the blow-pipe O, havingthe branch 0, containing the conduetorc, and the tip a, electrically connected directly with the battery, as described.

5. The combination, with the lighting-tip,

of the sheath F, havi an the flap f and the guard f, as described.
